If you are looking for the source code to the Xamarin AndroidX bindings, it is available in the branch: AndroidX @ xamarin/AndroidSupportComponents
The Migration package helps apps which are transitioning to AndroidX but haven't yet updated their own source code to the new AndroidX API's, or still depend on third party libraries which have not been updated to use the new AndroidX API's.
You should add the Xamarin.AndroidX.Migration NuGet package to your Xamarin
Android application project and any Xamarin.Android library projects it
references.
You will need to keep your existing references to Xamarin.Android.Support.* NuGet packages as any remaining usage of the old Android Support API's will require this for compiling before the migration build step does its job. The Android Support libraries will not be bundled into your apk.
The migration package contains a validation step which helps ensure you have references to all of the AndroidX NuGet packages that the Android Support library NuGet packages you reference in your app map to.
You will see a build error generated telling you which packages are missing which you need to add.
As soon as all of your own source code, layout files, proguard configurations, and manifest files are converted over to using the new AndroidX API's, and all of the libraries you depend on have done the same, you can safely remove the AndroidX Migration NuGet package along with all of the old Android Support library NuGet packages.
